臺灣博碩士論文加值系統

台灣地區位於板塊擠壓區，地質構造複雜，岩盤常存在各種弱面；基礎置於軟弱的岩石上，岩盤可能因基礎荷重而破壞，同時產生較大的沉陷。因此軟弱岩石的承載行為需加以研究。本研究從實驗與理論兩方面系統性探討軟弱岩石的承載行為。在實驗方面之研究大致可分為二類：(1) 人工岩石基本參數實驗：求得人工岩石的基本力學性質；(2) 基礎承載實驗：觀察基礎承載行為，並可測得基礎之承載力與沉陷量。在理論分析方面研究包括：(1) 蒐集各種基礎承載理論，並歸納其適用性；(2) 進行有限元素法分析，並將數值分析結果與實驗比較，以評定所採用分析模式之適用性；(3) 進行數值參數分析，探討不同因素之影響程度；(4) 根據基礎承載實驗結果之觀察及破壞機制的判定，擬定簡化預測軟弱岩石承載力的模式。

In this study the behavior of rock (essentially, weak rock
) subject to foundation loading is studied through analytical
and experimental approaches to provide fundamental understanding
and guidelines for analysis and design in engineering aspect.
In the analytical approach, a systematic survey is performed
to evaluate and characterized the existing analytical methods
and, as a result, to determine a proper analytical method. A
representative material model describing the behavior of rock
is to be developed. Based on the proposed material model, a
series of parametric study is then performed to investigate the
effect of related parameters. The results of this research
include: extensive literature review, setup of numerical analysis as well as experimental study to observe the failure patterns and associated mechanisms, which will provide useful information for later analyses and experiments.
